Any U.S. citizen or national who is not currently incarcerated is eligible to buy insurance through the exchanges.

Discrimination on the basis of gender or pre-existing condition is not allowed within the exchange marketplace.

Exchange participants may qualify for tax credits depending on their household income and the size of their families.

Participants will be able to choose a plan from four categories: bronze, silver, gold and platinum. The categories are distinguished by the average percentage of costs they cover. Stand-alone dental plans and catastrophic plans will be offered as well.

Participants can find out through the HealthCare.gov website whether they are eligible for Medicaid, the Children's Health Insurance Plan or assistance with a private plan offered through the exchanges.

Further information and resources are available through Marketplace.cms.gov, HealthCare.gov and the Health Insurance Marketplace Call Center.
